Hello!
I'm new in linux and I try to install ubuntu in virtualbox.
But I met a very serious error.
I have reserch as I can to try to solve it.
And I find I can made virtualbox work by reinstall it and clean the chache,but just flash in the pan.
whenever I reboot my computer,I have to do this once more to make it work.
It's unacceptable,So I really want someone can help me to solve it.
Here is the log and image and sorry for my poor ENGLISH,it might made you read so hard.
blessed.

See Diagnosing VirtualBox Hardening Issues, end of post 3 and post 4.

You don't have 3rd-party Antivirus, which is good. Windows Defender works well and does not interfere with Virtualbox.

Look on your computer for nanny-style web-safe security software, Trusteer Rapport, HPprotectTools, stuff like that, or non-really-mainstream vpn or access software. The log does not say what program is causing this, it's digging into Virtualbox too early; you'll have to try to discern.
